of inhabited quarters and to the circulation of air within such quarters.

An object of my invention is to provide a fan assembly which may be mounted in a window of any room and may be utilized either to circulate air within the room or to induce air to enter the room from the outside atmosphere and at the same time to deliver such outside air into the room at fairly high velocity, thus causing circulation of air within the room.

My new invention will be understood from the following specification taken in connection with the attached drawing in which:

Figure 1 illustrates a vertical cross-section taken through the center of the fan assembly.

Figure 2 illustrates a vertical cross-section in the plane 2- -2 of Figure 1.

Figure 3 illustrates a vertical cross section in the plane 33 of Figure 1.

Figure 4 illustrates a vertical cross-section in the plane 4& of Figure 1.

Referring to the drawing, the numeral 8 indicates a plate, vertically disposed, which may be made of wood or metal or other suitable material and which is shown disposed in a window, the lower portion of the plate 8 being supported on the window sill 9. The window sash I 8 is shown supported by and in contact with the upper edge of plate 8. All of that part of the apparatus to the right of the plate 8 is located within a room, while all of that part of the apparatus shown to the left of the plate 8 is located in the outside atmosphere. A circular opening I I is cut through plate 8. Supporting rods i2 penetrate plate 8 and are disposed vertically with respect to the plane of plate 8 and are attached to plate 8 and extended horizontally in both directions from plate 8. To the extremity of the portions of supporting rods I2 which extend into the outside atmosphere is attached a vertically disposed circular plate l3 the plane of which is parallel to the plane of plate 8. A horizontally disposed cylinder M, the diameter of which is less than the diameter of plate I 3 and the outside diameter of which is approximately the diameter of the opening II, is maintained in position by guides i5 and i6 which are rigidly attached to cylinder M and are free to move along supporting bars l2. A cylinder H is horizontally disposed and rigidly attached to supporting bars l2 by means of brackets iii. A motor l9, to the shaft of which is attached a propeller type fan 2!], is supported by supporting brackets 2| which are rigidly attached to both the motor and the 1936, Serial No. 96,406

cylinder H, The shaft of the motor is horizontally disposed and in such position that the fan 20 may be mounted within the cylinder l1. Deflector plates 22 are shown attached to cylinder ll. These deflector plates are arranged ver- 5 tically, their planes being perpendicular to the horizontal and they are so attached to the cylinder I! that the position of the plane of each of them may be independently changed with respect to the plane of plate 8.

The motor i9 is reversible and is provided with a suitable switch, not shown, by which the motor may be rotated in either direction. l

The cylinder l4 may remain in the position shown in solid lines or may be moved to the position shown in dotted lines or to any intermediate position. When the cylinder I4 is in the position shown in solid lines, the fan may be operated to deliver airin either directionthrough the cylinder [1 and will thus cause rapid circulation of the air within the room in which the fan is located. When the cylinder l4 has been placed in the position shown in dotted lines the fan may be operated to deliver air from the room in which it islocated through cylinders I1, and M to the outside atmosphere but in such case will preferably be used to deliver air from the outside atmosphere into the room, thus not only ventilating the room but at the same time causing circulation of air within the room. 30

Normally during the daytime the cylinder M will be maintained in the position shown in solid lines and the fan will be operated to circulate the atmosphere within the room during the daytime at which time the air within the room would normally be cooler than the outside atmosphere. After the sun has gone down and the temperature of the outside atmosphere has dropped to a temperature below that of the atmosphere within the room, the cylinder M will preferably be moved into the position shown in dotted lines and the fan will be operated to deliver air from the outside atmosphere through the cylinders II and I7 and thence through deflectors 22 into the room, thus efiecting both the cooling of the room and the agitation of the atmosphere of the room. 7

It should be noted that when the cylinder i4 is in the position shown by dotted lines this cylinder, together with the cylinder ll, form a continuous free open passageway through which air 50 may be delivered either from the room to the outside atmosphere or from the outside atmosphere to the room and that when the cylinder I4 is moved into the position shown in solid lines the effect is to close this passageway to the out- 55 side atmosphere and to open this passageway to circulation of the atmosphere of the room.

In accordance With the above it is apparent that my new invention provides a fan assembly which may be alternately, as desired, utilized either to circulate the atmosphere within a room or to deliver air from the outside atmosphere into 7 1 both ends in communication with the interior of the room.

When delivering air from the atmosphere into;

the room it is, of course, necessary that some opening'be provided from the room to the atmosphere through which such delivered air may exit from the room to the atmosphere. Some other window, or a part of a window shown in the drawing, may be utilized for this purpose.

The cylinder l4 being placed in a position midway between the two positions in which it is shown will permit the circulation of some of the atmosphere of the room while at the same time some outside air may be delivered into the room. V V

The horizontal length of plate 8 will be made adjustable and'it may, therefore, be installed in any window. Obviously the fan assembly could be permanently installed in the outside wall of any inhabited quarters rather than temporarily installed in a window.

While I have shown in detail a form of my new apparatus I do not propose to limit myself to these details but rather propose to claim all the novelty which is inherent in my new apparatus. V

I claim:

1. An air circulating fan assembly comprising two co-axial cylindrical members, one of said members supporting a motor driven fan within the room, the other of said members extending through an opening in one wall of the room to provide an air inlet conduit, one of said members being movable in one direction with respect to the other member to provide a radial opening within the room communicating with the suction side of said fan, and means cooperating with said movable member for closing the inlet end of said conduit, whereby the operation of said opposite direction to close said radial opening and open the inlet conduit, whereby the operation of said fan will draw fresh air from the atmosphere into said room.

2. An air circulating fan assembly comprising a fan casing forming a short conduit open at 'room adjacent a suitable opening in one wall thereof, a co-axial conduit slidable longitudinally in said opening into engagement with said casing to form therewith a continuous passageway from the atmosphere to the interior of said room, whereby the operation of said fan will draw fresh air from the atmosphere into said room, said conduit being slidable longitudinally out of engagement with said casing, and means for closing the outer end of said conduit when in the latter position, whereby the operation of said fan will cause the circulation of the air within the room. a

3. An air circulatingfan assembly comprising a fan casing forming a short conduit open at both ends in communication with the interior of a room, a motor-driven fan in said casing, a series of guide rods for supporting said fan and casing within the room adjacent a suitable opening in one wall thereof, a fixed plate carried at the opposite end of said guide rods at a point outside the room, a co-axial conduit in said opening slidable longitudinally on said guide rods into engagement with said casing and out of engagement with said fixed plate, to form a con- 7 tinuous passageway from the atmosphere to the interior of said room, whereby the operation of said fan will draw fresh air from the atmosphere into said room, said conduit being slidable longitudinally out of engagement with said casing and
